“Some ancient eukaryote swallowed a photosynthesizing bacteria and became a sunlight gathering alga. Millions of years later one of these algae was devoured by a second eukaryote. This new host gutted the alga, casting away its nucleus and its mitochondria, keeping only the chloroplast. That thief of a thief was the ancestor or Plasmodium and Toxoplasma. And this Russian-doll sequence of events explains why you can cure malaria with an antibiotic that kills bacteria: because Plasmodium has a former bacterium inside it doing some vital business.”

“In 1494, King Charles VIII of France invaded Italy. Within months, his army collapsed and fled. It was routed not by the Italian army but by a microbe. A mysterious new disease spread through sex killed many of Charles’s soldiers and left survivors weak and disfigured. French soldiers spread the disease across much of Europe, and then it moved into Africa and Asia. Many called it the French disease. The French called it the Italian disease. Arabs called it the Christian disease. Today, it is called syphilis.”

“The extra clutter adds no important insight; instead, it offers more clutter in which erros can lurk.”

“Coal, oil and gas are called fossil fuels, because they are mostly made of the fossil remains of beings from long ago. The chemical energy within them is a kind of stored sunlight originally accumulated by ancient plants. Our civilization runs by burning the remains of humble creatures who inhabited the Earth hundreds of millions of years before the first humans came on the scene. Like some ghastly cannibal cult, we subsist on the dead bodies of our ancestors and distant relatives.”

“Two hallmarks of Homo Sapiens are decoration and self-identification.”

“The squid has even evolved a special place to house the bacteria - a structure scientists call a 'light organ' located inside the mantle. But the bacteria don't just set up house and begin to party. When the first batch of bacteria arrive in their new digs, they have work to do.The light organ has been partially prepared for the bacteria's arrival, but the final touches won't occur until the newly arrived bacteria get things started. It's as though they've arrived in a new house but only the frame is up. The bacteria themselves have to do the finish work.”

“The greatest and most important problems of life are all in a certain sense insoluble…. They can never be solved, but only outgrown…. This ‘outgrowing’, as I formerly called it, on further experience was seen to consist in a new level of consciousness. Some higher or wider interest arose on the person’s horizon, and through this widening of view, the insoluble problem lost its urgency. It was not solved logically in its own terms, but faded out when confronted with a new and stronger life-tendency.”
